Top speaker assembly causes phone to boot loop + home button error

my iPhone 7 recently had a screen replacement, worked fine until like later october when front camera stopped working. i re seated the top speaker and camera, then the top speaker stopped working. recently the device entered a boot loop. i unplugged the top speaker/camera and it booted however the home button stopped working. re plugging the top speaker(after unplugging battery) will continue boot looping when re plugging battery. it is the original home button and 80% sure its the original top camera + speaker
